BOTTLE-CLOSURE.

Specification of Letters Patent.

Application filed February 24, 1908. Serial No. 417,487.

To all whom it mag concern:

Be it known that we, oBnRr M. CAUFF- MAN and lVELLrNeroN Bnsr, citizens of the United States, residing at Centerville, in the county of St. Joseph and State of Michigan, have invented certain new and useful Improrements in Bottle Closures, of which the following is a specification.

This invention relates to milk jar closures.

Dairymen, milk dealers and others are aware that milk will not sour as quickly in an open container as in a hermetically sealed vessel, and one of the objects of our invention is to improve existing conditions manifest in the handling of milk in hermetically sealed bottles and jars in which the milk is served to consumers. w, Another object of the invention resides in the provision of a closure of the nature stated embodying such characteristics that the closure will permit of the ingress of air into the container to intermingle with the milk, purify the air in its passage into the container and yet prevent the ingress of insects or other foreign matter detrimental to the wholesomeness of the commodity.

With the above and other objects in view, the present invention consists in the, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacrificing any of the advantages thereof.

In the drawings :-Figure l is a vertical sectional view of the neck portion of a jar illustrating the preferred form of our invention. Fig. 2 is a face view of the closure. Fig. 3 is a sectional view of a modified form of the closure.

Referring now more particularly to the accompanying drawings, the reference character 1 indicates the neck portion of a milk jar or bottle having an internal annular shoulder 2 for the support of the closure. The bottle or jar is of any well known construction, and. our closure is particularly adapted to the bottles and jars now in com mon use.

Our preferred form of closure consists of a paste-board or other pliable disk-3 having perforations 4 through which the air may pass into the bottle. On one face of the disk 3 We cohesively secure apiece of cotton or other suitable fabric 5' which does not preclude air from passing into the bottle or jar but which effectually guards against the ingress, intothe bottle or jar, of insects and such matter as would be liableto contami-- nate it with impurities.

We prefer to sterilize the fabric or other material 5 in an antiseptic bath prior to its application to the pliable disk 3 so that the air entering the bottle may be subjected to a purifying agent or action and filtered in its passage into the bottle orjar.

In the use of the closure hereinbefore described, the fabric side of the closure will be preferably disposed upon the outside, as shown in the drawings.

If preferred we may employ two disks 6 and 7 provided with alining perforations 8 and with a disk or other shaped piece of fabric 9 between them, as disclosed clearly in Fig. 3. This modified form of the invention embodies all of the essential characteristics of the preferred form of the closure.

What is claimed is 1. A mi'lk jar closure consisting of a per:

3. A milk jar closure consisting of a perforated disk and a thin sheet of filtering ma-' terial adhered to the disk and covering the perforations toprevent discharge of the con tents of the jar through the perforations but through said perforations.

4. A milk jar closure consisting of a perforated disk, and a disk shaped sheet of filpermitting of the ingress of air into the jar ering sa'id perforations, the disks being of fines, in presence oftwo witnesses. the same size. 1 ROBERT M. CAUFFMAN.
